installing Postfix on Ubuntu as an internal mail server

I had a client who wanted to have an internal email server for sending outbound emails. This email server would be used for sending scans (via scan to email) where the copier didn't support TLS and the email server required TLS and also for email blasts (where users send out mass emails via a local software program like WorldCast).

The rest of the lines are set by default. Save, exit, and reload the configuration file to put your changes into effect:

sudo /etc/init.d/postfix reload

Of note - this is an outbound only email server. Separately, you need to make sure you can send out on port 25 (via your firewall and ISP) and that you're not violating any SPF records with this server (or you may need to adjust SPF records).
